The resettlement of refugees from Middle Eastern countries, particularly Syria, has been at the center of a heated political debate after President Barack Obama last year pledged to resettle at least 10,000 refugees from the war-torn country in the United States.

But refugees from Myanmar, whose leader, Aung San Suu Kyi, visited Washington last week, have quietly outpaced Syrian arrivals in recent years, even as Syria's civil war intensifies, with an increasing number coming from the marginalized Rohingya Muslim community, according to State Department figures.

From October 1, 2015, to September 15 of this year, 11,902 Myanmar nationals were resettled in the United States, according to figures from the Refugee Processing Center, operated by the State Department, compared with 11,598 arrivals from Syria over the same period.

That was out of a total of nearly 79,600 refugees who arrived in the United States in that period. The largest group, numbering just over 15,000, was from the war-torn Democratic Republic of Congo. Arrivals from Syria, where Islamic State and other radical groups are active, are subject to additional screening processes, according to the White House.

State Department figures show the number of Rohingya arrivals from Myanmar jumped from just over 650 in fiscal 2014 to 2,573 last year. This year, 2,173 had arrived as of September 15.

During a meeting with Suu Kyi in the Oval Office last Wednesday, Obama announced that the United States would remove sanctions originally imposed on the country in 1997, when it was ruled by a military junta that brutally suppressed pro-democracy movements and showed little regard for human rights.

The decision raised alarm among rights groups, who are concerned about the plight of the stateless Rohingya among other ethnic minorities.

Long-persecuted minority

The Rohingya have long been persecuted in Myanmar, where they are viewed largely as illegal immigrants from Bangladesh, though many have lived in the country for generations.

Increased freedom of speech since the military stepped back from direct rule in 2011 has allowed for the unleashing of long-held anti-Muslim sentiment.

Around 125,000 remain confined to temporary camps in Myanmar's Rakhine state following waves of deadly violence in 2012 between Buddhists and Muslims. Most were stripped of their ability to vote in last year's election.

Most Rohingya tend to come to the United States after spending years in Muslim-majority Malaysia and being granted refugee status by the United Nations.

Nasir Bin Zakaria, who founded the Rohingya Culture Center in Chicago — home to one of the largest populations of Rohingya in the United States — estimates that there are just over 1,000 Rohingya in the city. He fled Myanmar after being forced to work as a porter when he was 16, he said.

Nasir Bin Zakaria said that the ability to move around freely and legally made life in Chicago far better than in Myanmar and Malaysia, but it is not without its own challenges for refugees. The city of 2.7 million is struggling with a surge of killings, with 509 killings this year, according to the Chicago Police Department.

Newly arrived children from refugee families, unfamiliar to the United States, are an enticing target for gangs looking to recruit, said Melineh Kano, executive director of RefugeeOne, a resettlement agency in Chicago.

"When we are selecting neighborhoods, we have to be very careful about the crime rate and gang recruitment, because the majority of refugees come with kids," she said. "You either join or you get beaten up."
